Example 3: If you want to increase the number of printed sheets in continuous mode (to decrease
the interval of warming up operations during printing)
This can be done by increasing the temperature range in which printing is possible.
(a) Increase the values of parameters 552 to
555 (maximum temperatures) by 10 each,
and increase the value of parameter 738
(minimum temperature) by 20 (the heat
roller maximum temperature is increased
by 10°C compared to the default value,
and the heat roller temperature is
decreased by 10°C).
(b) Increasing the range between the
minimum and maximum heat roller
temperatures makes it possible to
increase the number of sheet printed
continuously.
Note
The fusing performance may become worse
because the heat roller minimum temperature
has been decreased. Do not increase the heat
roller minimum temperature parameter by more
than 20.
